Bone grafting is the replacement or augmentation of that portion of the jawbone that is needed to anchor the implant. When bone grafting is performed in the surgical site, it also promotes new bone growth. When successful, bone grafting will restore both the height and width of your jawbone.
If you are considering an implant but dental x-rays and/or CAT scan show that you have a thin jawbone as a result of bone loss then a graft will be necessary. Our teeth help to maintain bone density by a natural renewal process. This ensures normal bone growth and healthy tooth tissue. Bone grafts are are highly successful procedure. They involve the grafting of bone from one area of your body into your jawbone to increase its width and depth.
Your jaw may show advanced bone loss as a result of the aging process, prolonged denture wear, missing teeth, periodontal gum disease or as a result of an accident.
If you lose a tooth due to an accident or injury, then what typically happens is that the area around the missing tooth will recede and the actual jawbone will start to shrink. If a person has lost several teeth and has not replaced them, their facial jaw line will appear lined and "sunken in". This aged appearance is obviously, both undesirable and unnecessary. A solution to this is a dental implant or multiple implants. However, depending upon the extent of bone deterioration, this may have to be combined with a bone graft.
Ideally, bone will be grafted from your own body although a synthetic alternative can be used. There are four types of bone grafts: Autogenous or Autografts, Allografts, Xenografts and Alloplastic.
